These are the clearest photos yet of the Aprilia Tuono V4. Snapped by Motoclismo.it, they reveal a bike that shares its frame, engine and tailpiece with the Aprilia RSV4 R, but adapts a very angular new tank, flat bars, a smaller exhaust and a tiny bikini fairing. It looks like the Tuono is also going to ditch the RSV4's fancy monoblock calipers in favor of cheaper, but still radial Brembos. There's HD video of the new Tuono in action below. >

Motociclismo says to expect a retuned engine with earlier torque delivery at the expense of peak power and a weight saving of 4-5kg, bringing the Tuono's total weight down to around 179kg (395lbs).

The bike in these photos appears to be pretty much production ready, wearing angular radiator shrouds that mimic the lines of the RSV4's fairing and a bikini fairing that, under its tape, looks like it may replicate the superbike's triple headlight arrangement.

The black engine cases indicate that this Tuono is based on the cheaper RSV4 R rather than the Aprilia RSV4 Factory, which uses brown Magnesium cases. That's not a bad thing, the R retains virtually all of the Factory's ability, while retailing for $5,000 less. The Tuono retains the RSV4's massive swingarm and frame, but does appear, at least in these photos, to be wearing different suspension.
